This epoxy has a smooth consistency for easy mixing, will begin to harden in about 5 minutes and will not drive your protein skimmer crazy. Colored like coralline algae to mimic the natural color and will hold it's color well in your water. Cut, Knead, Squish, Mount, Cured in minutes! Comes in a 2oz Stick.

When stacking rock in my salt water tank, I’ve used the product almost like you would use a filler. The fill in the un even spots on the rock so they will stack firmly on each other with no risk of it falling over. When it cures, it turns a little bit of a lighter purple so that when you rock becomes covered in coralline algae, you will not be able to see the epoxy anymore. I would suggest disposal latex gloves as this can be hard to wash off your hands and they will be a little purple for a while without using the gloves.
